• 需要依赖的maven

 <!-- https://mvnrepository.com/artifact/redis.clients/jedis -->
        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
            <version>2.9.0</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.apache.commons/commons-pool2 -->
        <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-pool2</artifactId>
            <version>2.3</version>
        </dependency>

• 简单案例

     //设置ip地址和端口
        Jedis jedis = new Jedis("127.0.0.1", 6379);
        //保存数据
        jedis.set("name", "张三");
        //获取数据
        String value = jedis.get("name");
        System.out.println(value);
        //释放资源
        jedis.close();

• 通过连接池连接的简单案例

   //获取连接池的配置对象
        JedisPoolConfig config = new JedisPoolConfig();
        //设置最大的连接数
        config.setMaxTotal(30);
        //设置最大空闲连接数
        config.setMaxIdle(10);

        //获得连接池
        JedisPool jedisPool = new JedisPool(config, "127.0.0.1", 6379);
        //获得核心对象
        Jedis jedis = null;

        try {
            jedis = jedisPool.getResource();
            jedis.set("productName", "电脑");
            System.out.println(jedis.get("productName"));
            System.out.println(jedis.get("name"));
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
         //释放资源
            if (null != jedis) {
                jedis.close();
            }
            if (null!=jedisPool){
                jedisPool.close();
            }
        }
